Which risk increases when Roman road pavers used poorer quality aggregate materials during construction?

💡 Explanation

When lower quality aggregates are used, differential thermal expansion occurs because temperature variations cause non-uniform expansion and contraction rates between the aggregate and paving material, leading to cracking. Therefore increased cracking from differential expansion results, rather than drainage, mortar, or dust issues which relate to alternative road failures.
